This provides bit and common code to control autostrip state.
Requirement for this is coming from Wa_14026781792. We are writing
register for Wa_14024997852 and since this register is nonmaskable
the bit needs to be written always. Helper takes care to touch only
required bits.

Unfortunately, Yf + CCS isn't supported on gfx12. Tests fail and systems
hang in the CI with this enabled. The simulator also complains about
this combination on tests such as:
dEQP-VK.api.image_clearing.core.clear_color_attachment.multiple_layers.r4g4b4a4_unorm_pack16
dEQP-VK.api.image_clearing.core.clear_color_attachment.single_layer.r4g4b4a4_unorm_pack16_200x180_sample_count_2

When the system is under memory pressure (which can happen, for
example, during CI runs), don't immediately give up the exec ioctl
(which, for Vulkan, will result in the device being declared lost).
Instead, retry a little bit just like we do for i915.ko.
This is a trade-off.
One of the reasons to *not* have unified behavior regarding ENOMEM
between i915.ko and xe.ko is the fact that xe.ko uses vm_bind, so if
the user tried to bind more memory than it is able to, we'll just keep
getting ENOMEM as long as we retry the ioctl. We now have a retry
limit, so we'll eventually return the error.
On the other hand, if the problem is other applications consuming all
the memory, having the retry loop may really help avoid unnecessarily
marking the device as lost, since one of our retries may eventually
succeed.
I believe the tradeoff of "we'll now eventually succeed in some cases
where it's possible to succeed, at the expense of retrying for a few
seconds until giving up in cases where we would never be able to
succeed" is an improvement.
If xe.ko ever gives us a way to differentiate between the two
different reasons for ENOMEM, we'll be able to make things much
better. We can also tune our timeouts if needed.

If the ioctl is returning ENOMEM, incessantly retrying does not seem
to be the best way to proceed. After the second retry, sleep 0.1ms,
then more each time, giving the CPU some time to run the other threads
and processes, in the hope that whatever is eating all the memory
might eventually return it.
If the problem is the current thread, then busy looping won't help
either, so here we at least save some power before the user kills the
app.
v2: Adjust the control flow and the sleep time.

In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>
See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in
And this causes build errors when building for C23:
-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
123 | #define unreachable(str) \
| ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
456 | #define unreachable() (__builtin_unreachable ())
| ^~~~~~~~~~~
-----------------------------------------------------------------------
So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.
Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.
This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.
All the instances of the macro, including the definition, were updated
with the following command line:
git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
while read file; \
do \
sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \

Fixes#13241, where iris_bufmgr occasionally deadlocks while allocating buffers.
The deadlock happens when iris_bufmgr.c calls intel_aux_map_unmap_range while
holding the bufmgr lock, with a range that includes pages that were never created,
which can happen because the iris_resource that adds aux mappings will sometimes
use a slightly larger buffer with an offset to ensure the resource is aligned
correctly.

We were not using the minimum values from devinfo for anything. For

MAX2 of that with 1 when tessellation is enabled so we have at least

is already non-zero (and updated by the previous patch).
This will have the side-effect of raising the minimum number of URB
